Idwer:
    the vendor(ASUS) EFI software can detect the DIMM,and I power
cycle after moving from EFI,to coreboot.
I will try a kingston ddr3 1333 tomorrow.
      thank you very much !

This means that agesa code can't find a ddr3 module, does the vendor
EFI software detect the DIMM? Did you power cycle after moving from
EFI to coreboot?

>From the code in
src/vendorcode/amd/agesa/f15tn/Proc/Mem/Main/mmExcludeDimm.c on and
around line 236:

  // if all dimms on all nodes are excluded, do fatal exit
  if (RefPtr->SysLimit == 0) {
    PutEventLog (AGESA_FATAL, MEM_ERROR_NO_DIMM_FOUND_ON_SYSTEM, 0, 0,
0, 0, &NBPtr->MemPtr->StdHeader);
    SetMemError (AGESA_FATAL, NBPtr[BSP_DIE].MCTPtr);
    ASSERT (FALSE);
  }
